Description

Technical Field

[0001] This utility model relates to the field of heat sink fin technology, specifically a stamping fixture for processing heat sink fins. Background Technology

[0002] Heat sink fins are thin metal sheet structures that increase the heat dissipation area. By expanding the contact area with the air, they accelerate heat transfer. Combined with natural convection or forced air cooling by a fan, they improve heat dissipation efficiency and prevent equipment from degrading or being damaged due to overheating. They are widely used in electronics, machinery, automobiles and other fields.

[0003] Stamping fixtures for heat sink fin processing are specialized tooling fixtures used for stamping heat sink fins. They typically consist of an upper die, a lower die, and positioning components. In conjunction with stamping equipment, pressure is applied to deform the material into a preset shape, ensuring the fin's dimensional accuracy, consistency, and structural integrity. This improves production efficiency, reduces human error, and is widely used in the mass production of heat sink fins.

[0004] Existing stamping fixtures for heat sink fin processing still have the following problems: it is inconvenient to accurately determine the positioning and pressing position. When it is necessary to press the upper die of the fixture, it needs to be placed directly below the cylinder output end. Usually, the user needs to manually align it, but manual alignment is very difficult, time-consuming and laborious. In order to address the above problems, a stamping fixture for heat sink fin processing is proposed. Utility Model Content

[0031] Combination Figures 1-3 and Figure 7This utility model discloses a stamping fixture for processing heat dissipation fins, comprising a cylinder 1 and a base plate 5. Connecting rods 7 are fixedly connected to the left and right sides of the top front end of the base plate 5. A connecting plate 12 is fixedly connected to the top of the connecting rods 7, allowing for more stable installation of the two connecting rods 7. A connecting piece 8 is fixedly connected through the outer ring of the connecting rods 7, allowing the connecting piece 8 to be installed. The cylinder 1 is fixedly connected to the top rear end of the connecting piece 8. A push rod 13 is fixedly connected to the output end of the cylinder 1, allowing the cylinder 1 to drive the push rod 13 downwards, pressing the upper mold 2 of the fixture. The top of the product base 9 has evenly distributed grooves 16, the inner wall of which is slidably connected to the product fins 10, allowing the product fins 10 to be installed. Holes 11 are provided through the four corners of the bottom of the product base 9, facilitating subsequent installation or fixing of the product base 9.

[0032] Combination Figures 1-6 and Figure 8 A groove 6 is provided at the top center of the base plate 5. An anti-slip plate 14 is fixedly connected to the left side of the inner wall of the groove 6. The anti-slip plate 14 is used to determine the accurate position. A T-shaped slider 15 is slidably connected to the inner wall of the groove 6. A product base 9 is fixedly connected to the top of the T-shaped slider 15. The product base 9 can move stably by the cooperation between the T-shaped slider 15 and the groove 6. A product fin 10 is evenly distributed and slidably connected through the top of the product base 9. A tooling shell 3 is slidably connected to the outer ring of the product fin 10. A finned heat sink 4 is evenly distributed and slidably connected to the inner wall of the tooling shell 3. A tooling upper mold 2 is fixedly connected to the top of the finned heat sink 4. The tooling shell 3 allows the product fin 10 and the finned heat sink 4 to cooperate and press. The right side of the anti-slip plate 14 is in contact with the T-shaped slider 15. The anti-slip plate 14 is used to determine the moving position of the T-shaped slider 15 and ensure that the tooling upper mold 2 is directly below the cylinder 1.

[0033] The working principle is as follows: First, insert the product fins 10 into the groove on the surface of the product base 9. Then, insert the product fins 10 into the tooling housing 3 from below. Next, insert the tooling upper mold 2 and the finned heat sink 4 into the tooling housing 3 from above. By setting the slide groove 6, the T-shaped slider 15 at the bottom of the product base 9 can be inserted into the slide groove 6. By blocking the anti-slip plate 14, the T-shaped slider 15 stops sliding. At this time, the tooling housing 3 slides directly under the cylinder 1, thus ensuring that the subsequent pressing force is even. Then, start the cylinder 1. The output end of the cylinder 1 drives the push rod 13 to move downward, thus applying pressure. The finned heat sink 4 is inserted into the workpiece base. The tooth tip taper deforms the surface and squeezes the workpiece firmly. Then, the T-shaped slider 15 is pulled out of the slide groove 6. Then, the tooling upper mold 2 and the finned heat sink 4 are pulled out and rotated 180 degrees, and then put back into the tooling. Then, follow the above steps to press it again with the cylinder 1.
